Material Models for Steels
Material models, material data, capability of material data customization and process characterization are the advantages of DANTE software. The features and capabilities described in this section are the important factors why DANTE software can be used in part design, process design, and solve problems related to heat treatment processes.
The Dante material models were developed specifically to solve practical issues in the heat treatment industry, including these features:
Variation of alloy composition or austenite grain size effect on material hardenability
Initial microstructure volume fraction composition effect on part distortion
Carbon separation model to account for the rejection of carbon in ferrite
Effect of carbon content on local Martensite start temperature and transformation rate
High-temperature tempering model for high-alloy steels with secondary hardening including a carbide forming and coarsening models
Latent heat from phase transformations during heating and cooling
Non-linear Internal State Variable (ISV) Mechanical Plasticity Model accounts for non-uniform plastic deformation from phase transformations and Bauschinger effect
Mechanical properties are a function of phase, carbon content, temperature, strain, and strain rate
Mixture law accounts for stress state of a material composed of the different microstructural phases
Transformation-induced plasticity (TRIP) model
Analyze gas carburization and low-pressure carburization (LPC) schedules
Carbide growth and decomposition kinetics model useful for designing LPC recipes
